Embodiment Construction
[0074] In the embodiment of the present invention, according to the received neighboring cell list reported by the cell, all the cells that report the neighboring cell list are divided into at least one set of mutually adjacent cells, wherein any two cells in the set of mutually adjacent cells are mutually adjacent cells; Determine at least one frequency band number corresponding to a cell that has not allocated a frequency band number in a set of mutually adjacent areas, wherein the frequency band numbers of any two cells in each set of adjacent areas are different, and the frequency band number is used to identify the number of frequency bands that will be available according to the number of frequency bands. Sub-frequency bands obtained by equally dividing the allocated frequency band; for one cell, according to the determined number of the frequency band and the number of the frequency bands, send information capable of determining the position of the main sub-carrier to the...

The invention discloses a method and equipment for configuring frequency bands, which are used to solve the existing method of configuring frequency bands for adjacent cells in the prior art, which cannot ensure that the frequency bands occupied by the main subcarriers of all adjacent cells are orthogonal to each other, reducing the The communication performance of the users at the edge of the cell and the throughput of the entire system. The method of the present invention comprises: according to the neighbor cell list reported by the cell, all the cells that report the neighbor cell list are divided into at least one inter-adjacent cell set, wherein any two cells in the inter-adjacent cell set are mutually adjacent cells; Determine the frequency band number corresponding to the cell that has not allocated a frequency band number in at least one set of adjacent cells; for a cell, send information capable of determining the position of the main subcarrier to the cell according to the determined frequency band number and the number of frequency bands. The method of the invention can ensure that the frequency bands occupied by the main sub-carriers of all adjacent cells are orthogonal to each other, thereby improving the call performance of the edge users of the cell and the throughput of the entire system.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and equipment for configuring frequency bands. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system uses OFDMA (Orthogonal Frequency Division Multiple Access) technology as the transmission method for the downlink, and SC-FDMA (Single-carrier Frequency Division Multiple Access) for the uplink. address) technology as the transmission method. Since the uplink and downlink multiple access technologies utilize the orthogonality between frequencies, theoretically, users in this cell do not interfere with each other. The interference received by all users in this cell mainly comes from other adjacent cells that use the same frequency resources, especially the edge users of this cell, which are especially severely interfered by the same frequency of adjacent cells. Since the edge users of this cell are subjected to serious sam...
